Management of vasomotor symptoms in cancer patients.

Abstract

Many cancer treatments can lead to reduced levels of sex hormones, which in turn may cause vasomotor symptoms (VMS) such as hot flashes. These symptoms are associated with impaired quality of life, as well as suboptimal tolerability of and adherence to cancer treatment. Hormone therapy, performed by increasing estradiol or testosterone levels, is the gold standard for treatment of VMS. However, this approach is generally contraindicated in patients with hormone-sensitive cancers. Nonhormone agents with low to moderate efficacy in controlling VMS are available, but their use may be limited by side effects and tolerability. In this narrative review, the approach to VMS in cancer patients will be discussed. The evidence for various treatment options, including novel agents such as fezolinetant that target the hypothalamic thermoregulatory pathway, will be evaluated. Finally, special considerations in different patient populations based on cancer types (eg, breast, prostate) and age groups (eg, older adults) will be explored.
